Troubles trying to set up new Dahua HDW5231R-Z

hoomag · Jan 10, 2018

Hi all,

I'm fairly new to IP cameras and a bit technologically illiterate.

I purchased two Dahua HDW5231R-Z cameras after lurking on these forums along with a PoE switch and a used PC to be used as an NVR.

The cameras are connected to the PoE switch (which is connected to my router/modem) but my computers can't seem to pick up the cameras.

I followed the instructions in the manual as well as in this guide: Dense persons guide to the Dahua IPC-HDW5231R-Z but I'm unable to access the default IP addresses of the cameras through my browser.

The Config Tool included with the cameras are also unable to detect the cameras to give me their IP addresses.

I'm not sure what I'm doing wrong, or which part of my setup is defective. The PoE switch seems to be turned on and working fine. I tried using different PCs and none could pick up the cameras.

I'd appreciate anyone who can help me finally set these up.

Are the cameras powering up ?, can you hear any noise (IR cut filter or zoom) or observe the IR LED's ? Try in a dark room or cover the day/night sensor (I don't have that particular model). What switch are you using?, a lot of the cheap switches have only half their ports provide POE power. Make sure you are using the POE marked ports

I'll try that to make sure the cameras are actually turning on. If they're not, is there some button or switch I need to flick to power them on?

I don't think the PoE switch is the problem. The one I have is this one: https://www.amazon.com/BV-Tech-Port-Switch-Ports-Uplink/dp/B00WKRBI0W

The 4 ports are all marked PoE and switching which port I use doesn't seem to change anything.

Thanks for your suggestions

I don't have that camera but doubt it has or needs an on/off switch. Try different cable(s) next. The switch supports Auto-MDI/MDI-X. Do you have any other POE devices you can test switch with?.

I have tried with different Cat5e and Cat6 cables and still no luck.

What is the significance of Auto-MDI/MDI-X support? I just don't have to worry about what type of cable I use?

Unfortunately, I don't have any other PoE devices currently.

Correct, It means you can use a straight through cable or cross over cable without any problem. The average person would unlikely have a crossover cable.

These come with an IP address set as 192.168.1.xx if you are on a 192.168.0.1 gateway you will not see them.

What is the Dahua scan tool ?, that should find it regardless

If you have both cameras plugged in, and you have not changed their IP addresses, you're going to have an IP conflict. You should only do one camera at a time.

What OS are you using? Do you know how to tell what IP your computer has?

I believe the Dahua scan tool is the Config Tool, but it can't find my cameras.

I'm not very proficient when it comes to networking. How would I troubleshoot this then if I have a 192.168.0.1 gateway?

JDWX · Jan 11, 2018

A few ways to see it. But... If you can merely access your router login, you can look to see quickly what the 'local IP address' for your router and change it to 192.168.1.1 You will save it on the router, and reboot the PC so it can be handed the proper gateway. Then look for the cams. All you need to do.

NOTE, not the preferred way to do this, so see other posts in this thread for a "proper" way. I thought you had nothing else on the LAN except the cams, and thought this would be the easiest.

Windows 10 Pro.

Yeah I know how to determine my own computer's IP address.

Here's how my 192.168.x.x range is set up:

Right click the network icon in the task bar
Open Network and Internet settings
Choose Wi Fi or Ethernet depending on how you connect
Change adapter settings
Right Click Wifi or Ethernet
Properties
Click Internet Protocol Version 4 then click properties
Click Use the following address:

IP Address - something in the 192.168.1.2 - 192.168.1.254 range except 192.168.1.108
Subnet : 255.255.0.0 (allows you use the 192.168.0.1 gateway)
Gateway: 192.168.0.1

Then click ok.

You should be able to do 1 camera at a time after that.

In the Dahua IpConfig tool, at the top of the window you can change what range of ip's it will search. Since the cams are default at 192.168.1.108, this is the range you want to search. Click on the gear icon next to search settings.
Only plug ONE camera in at a time, until you change their IP address...which can be done in the IP config tool.

So, if your network is 192.168.0.1, the tool will be able to see the cams if they are on 192.168.1.1? Wow.. I had no idea.

This will mess up communications for all the other devices on your LAN.
Sorry to be blunt, but that's really bad advice.

Just change the PC IP address temporarily to be in the same range as the default address of the camera.
Or follow @looney2ns spot-on suggestion to ask the DH config tool to scan the default segment.

JDWX · Jan 11, 2018

Wow, had no idea. Thanks for that info. I traditionally just go into the cams directly and try not to use these software apps from whatever company. Certainly simplifies it.

Well, I know this, but it appeared from his question, they are the only thing there with a switch router and pc. So, that was my 3am, advice.
